Face The Nation: Chris Murphy, David Petraeus, Tom Perez

Missed the second half of the show? The latest on Connecticut Democrat says it's "incumbent" on the White House to present evidence on the imminent threat that led to Soleimani's death. Retired General David Petraeus says multiple Iranian attacks had gone largely unanswered in the months before the U.S. strike that took out Qassem Soleimani, a senior Iranian military commander. The DNC Chair says he disagrees with the contention that the party’s debate qualifications made it hard for minority candidates to make it to the debate stage.
